The staff members of RSC have participated in many significant projects, both inside and outside the realm of trains, that were seminal in the electronic transformation of railroad train control, including the present moves to PTC and CBTC systems.  This work has been done for railroads, transit authorities, industry suppliers, and government agencies throughout North America, either as prime or as a member of an engineering team.

Staff members have also completed safety programs for several international projects, evaluating rail products that need to meet differing standards throughout different parts of the world.


  • Safety Case (PTCSP) development for several PTC systems.
  • PTC Quantitative Risk Assessment per FRA Regulation.
  • PTC Safety Program Management and Execution per FRA Regulation.
  • PTC System Safety Assessment – Wayside, Carborne, Highway Crossing, Communications subsystems.
  • PTC Specifications for Contractor-executed Safety Programs
  • Independent Safety Assessor for various types of train control systems.
